RESEARCH ON ACTIVATED CARBON PREPARATION FROM MACADAMIA SHELLS USING H3PO4 ACTIVATING AGENT APPLIED FOR METHYLENE BLUE TREATMENT

Tóm tắt

Research on bio-activated carbon wastewater treatment material prepared from Macadamia shells using H₃PO₄ activating agent at the rate of 2H₃PO₄:1 piece of activated carbon is carried out through influencing factors of temperature and time. The research result of Methylene blue (MB) absorption ability at respectively optimal temperature and time of 500^oC and 60 minutes of activated carbon shows that 1g of activated carbon will absorb 116,91mg of Methylene Blue. The result shows that the color treating efficiency of the Methylene Blue (MB) is 97.11% corresponding to the color level reduced from 349.67 Pt-Co to 10,11 Pt-Co. Research result shows that bioactive carbon prepared from Macadamia shells and activated from H₃PO₄ can treat color in dyeing textile wastewater.
